| necrotic pulp | Necrosis of the dental pulp which clinically does not respond to thermal stimulation; the tooth may be asymptomatic or sensitive to percussion and palpation. Synonym: dead pulp, nonvital pulp. (05 Mar 2000) |

| necrotic rhinitis of pigs | An infection of the subcutaneous structures of the snout of swine which causes malformation of the face; it is frequently due to infection of wounds made for the insertion of metal rings to discourage or prevent the animal from rooting in the soil; Fusobacterium necrophorum plays an important role in this disease. Synonym: bullnose. (05 Mar 2000) |
| necrotising fascitis | <pathology> A serious soft tissue infection generally caused by Group A Streptococci (bacteria), but may also be caused by anaerobic bacteria (Peptostreptococcus, Bacteroides). This infection results in extensive soft tissue destruction (necrosis) of skin, subcutaneous tissue and muscle. Often surgical intervention (debridement) in combination with antibiotic therapy is required. Mortality rate is high particularly if treatment is delayed. Infection is often the result of a skin abrasion or puncture that becomes secondarily infected with Streptococcal bacteria. (27 Sep 1997) |
| necrotising glomerulonephritis | <pathology> A relatively uncommon (affecting 1 out of 10,000 people) form of acute glomerulonephritis that results in damage within the glomerulus of the kidney. There is rapid loss of kidney function with the formation of crescents on microscopic analysis (kidney biopsy). This disorder may result in acute glomerulonephritis or nephrotic syndrome, but ultimately results in renal failure and end-stage renal disease. Symptoms include smoky coloured urine (pyuria), decreased urine output, swelling and hypertension. Any conditions which can cause a vasculitis increase the risk of this disorder. Some examples include lupus, Goodpasture's syndrome, Henoch-Schonlein purpura, IgA nephropathy, membranoproliferative glomerulonephritis, anti-glomerular basement membrane antibody disease, history for malignant tumours and exposure to hydrocarbon solvents. (27 Sep 1997) |
| necrotizing angiitis | Inflammatory reaction of blood vessels resulting in fibrinoid necrosis of tissue, especially of the blood vessel wall. (05 Mar 2000) |
| necrotizing arteriolitis | Necrosis in the media of arterioles, characteristic of malignant hypertension. Synonym: arteriolonecrosis. (05 Mar 2000) |
| necrotizing cellulitis | Synonym: gangrenous cellulitis. (05 Mar 2000) |
| necrotizing encephalitis | Any encephalitis in which extensive brain necrosis occurs, e.g., acute necrotizing haemorrhagic encephalomyelitis. (05 Mar 2000) |
| necrotizing encephalomyelopathy | Subacute encephalomyelopathy affecting infants, causing dementia, spasticity, and optic atrophy; autosomal recessive inheritance. Synonym: necrotizing encephalomyelopathy, necrotizing encephalopathy. (05 Mar 2000) |
| necrotizing encephalopathy | Subacute encephalomyelopathy affecting infants, causing dementia, spasticity, and optic atrophy; autosomal recessive inheritance. Synonym: necrotizing encephalomyelopathy, necrotizing encephalopathy. (05 Mar 2000) |
| necrotizing enterocolitis | <radiology> NEC, pneumatosis intestinalis, submucosal: initial finding, mult. Cystic lucencies; looks like stool (!), subserosal: linear lucencies, portal vein: with or without transient; not significant, aetiology: preemie, perinatal stress, intestinal ischemia, survivors may develop intestinal strictures (12 Dec 1998) |
| necrotizing fasciitis | A rare soft-tissue infection primarily involving the superficial fascia and resulting in extensive undermining of surrounding tissues; progress is often fulminant and may involve all soft-tissue components, including the skin; usually occurs postoperatively, after minor trauma, or after inadequate care of abscesses or cutaneous ulcers. See: group A streptococcal necrotizing fasciitis. (05 Mar 2000) |
| necrotizing papillitis | <nephrology> Necrosis of renal papillae, occurring in acute pyelonephritis, especially in diabetics, or in analgesic nephropathy; renal failure may result. Synonym: necrotizing papillitis. (05 Mar 2000) |
| necrotizing scleritis | Fibrinoid degeneration and necrosis of the sclera. (05 Mar 2000) |
| necrotizing ulcerative gingivitis | An acute or recurrent gingivitis of young and middle-aged adults characterised clinically by gingival erythema and pain, fetid odour, and necrosis and sloughing of interdental papillae and marginal gingiva which gives rise to a gray pseudomembrane; fever, regional lymphadenopathy, and other systemic manifestations also may be present. A fusiform bacillus and Treponema vincentii can be isolated from the gingival tissues in large numbers and are felt to play a significant but poorly defined role in the pathogenesis. Synonym: fusospirochetal gingivitis, trench mouth, ulceromembranous gingivitis, Vincent's disease, Vincent's infection. (05 Mar 2000) |
